Question

I am querying the database for different values of prizes for an online loyalty scheme.

I know this is going to be a sort of easy question but Im still getting used to PHP so here goes…

This is what I have so far:

 <?php $sqlprize="SELECT prizeid FROM wp_scloyalty_orders WHERE  userid = '$user_id'";

            $resultprize=mysql_query($sqlprize); ?>

            <?php while($rows=mysql_fetch_array($resultprize)){  

                    query_posts('post_type=prizes&showposts=-1&p='.$rows['prizeid'].''); while (have_posts()) : the_post(); 
                    $my_meta = get_post_meta($post->ID,'_my_meta',TRUE);


                        //echo $my_meta['pointsvalue'];

                    endwhile; 
                    wp_reset_query();  



             } ?>

Basically I want it so each time it loops the database query it adds the value (my_meta[‘pointsvalue’] to an array, which I can use outside of the loop…

Thanks!

EDIT—————–

               <?php $purchasevalue=array(); ?>

           <?php $sqlprize="SELECT prizeid FROM wp_scloyalty_orders WHERE  userid = '$user_id'";

            $resultprize=mysql_query($sqlprize); ?>

            <?php while($rows=mysql_fetch_array($resultprize)){  

                    query_posts('post_type=prizes&showposts=-1&p='.$rows['prizeid'].''); while (have_posts()) : the_post(); 
                    $my_meta = get_post_meta($post->ID,'_my_meta',TRUE);            

                        $purchasevalue[] = $my_meta['pointsvalue'];         
                    endwhile; 
                    wp_reset_query();  

             } ?>

             <?php echo array_sum($purchasevalue) ?>

Thanks guys, sorted it in the end… is this a good way of doing it?

Answer 1

You can use array_push to add values to an array

$array = array();

while()....
   $my_meta = ....
   array_push($array, $my_meta);
end while;

//Your array is now
print_r($array);

Hope that’s what you’re looking for
